"I Don't Really Know How I Did That!"
Eberle, R. Scott
Teaching Children Mathematics, v21 n7 p402-411 Mar 2015
A "tessellation" is a pattern of geometric shapes that fulfills three conditions: (1) No gaps exist between the shapes; (2) The shapes do not overlap; and (3) The pattern can go on forever in all directions. Tilings (such as tiling a floor) are familiar to children and provide a rich resource at all grade levels for learning many different geometric concepts, such as angles and symmetry. This article examines how to organize open-ended tessellation activities in a way that supports the mathematical practices and concepts that teachers want students to learn for geometry. It also looks at the frequently overlooked importance of paying attention to what children find aesthetic in such activities.
